Penguins captain Sidney Crosby remains hospitalized after sustaining a broken jaw and losing teeth Saturday against the New York Islanders.According to coach Dan Bylsma, there is still no timetable for Crosby's return to the lineup.Crosby is in good spirits in the hospital and has been drinking a steady diet of healthy milkshakes.Bylsma reiterated that Crosby is not showing any concussion symptoms, which is something the team initially feared because of the velocity at which defenseman Brooks Orpik's shot struck Crosby's face.The postseason is scheduled to begin April 30, though because of a Black Keys concert at Consol Energy Center that day and the inevitability that the Penguins will open the playoffs at home (they lead the Atlantic Division by 16 points), the Penguins' Stanley Cup run almost certainly will begin May 1.• Crosby was named the NHL's No. 1 Star of the Month for March. While leading his team to a 15-0 record during the month, Crosby produced 25 points. He registered at least one point in 13 of the 15 games, and that number is slightly misleading as Crosby played less than a minute Saturday against the Islanders before being hit with a puck.• Defenseman Kris Letang, who hasn't played since breaking a toe against the Montreal Canadiens on March 26, skated before practice Monday. Bylsma said Letang also will skate by himself Tuesday before the morning skate. Letang, who broke a toe on the night he returned from a groin injury, continues to progress and could be back in the lineup at some point this week.• Bylsma did not offer an update on injured defenseman Paul Martin other than to say his Sunday surgery went well. Martin sustained a broken bone in his hand Thursday against the Winnipeg Jets. It was believed initially that Martin would miss six weeks, but the team since has revised that prognosis to four to six weeks. This is significant given that the playoffs begin in just more than four weeks.
